Reconfigurable intelligent surface (RIS)-empowered communication has become one of the most popular developments among these 6G technologies in recent years[1]}, [2]}, [3]}, [4]}. Supporting very high wireless channel capacity, expanding the signal coverage, reducing the bulkiness of the multiple antenna systems as well as the energy consumption, low-cost implementation and mitigating several negative effects of the wireless channel, such as multipath fading and the Doppler effect can be given as some of the reasons why RISs are been investigated thoroughly[5]}, [6]}, [7]}.
